Six months of heating pulls a lot through your ducts
Your furnace runs November through April here, six months of the year, with winter nights averaging 34°F from December through February. That is six months of air moving through the same ducts, and whatever is riding in that air settles on the inside walls a little at a time.
Cobb County has also logged 70 damaging wind events and 5 winter storms over the past ten years, and outages follow storms like these. When the furnace sits off during one and starts again, it pushes air through ducts that had gone still, and whatever settled there while the system was down moves back into the house.

- How often should air ducts be cleaned?
- There is no set schedule that fits every home, so most contractors go by condition rather than a calendar. If anyone in the house has allergies, if you just finished a renovation that kicked up drywall dust, or if you have pets, that pushes the timeline up. A musty smell when the air kicks on or dust visibly blowing out of the vents is the clearest sign it is time.
- Is air duct cleaning worth it?
- It is worth it if your ducts actually have a problem, dust blowing out of the vents, a musty smell when the air kicks on, or debris you can see when a vent cover comes off. Cleaning ducts that are already in decent shape will not lower your energy bills or stop allergies on its own. A contractor can look at the return and supply runs and tell you honestly whether cleaning will help your situation.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air whips to knock dust and debris loose so it can be pulled out, working through the supply and return runs one section at a time. The registers and grilles get cleaned too, and on some jobs the coil gets a look since buildup there affects airflow just as much as dirty ducts do. Each vent gets sealed off while that section is being cleaned so dust does not just spread to the next room.
